The Mizuno Shaft Optimizer and Swing DNA system has been the industry’s leading fitting system at local golf club level since its introduction in 2009. As the shaft itself measures all our data, the fitter doesn’t have to own expensive cameras or lasers – so you can be fitted by a local golf professional.

There are now more than 1,200 Mizuno Swing DNA centres across Europe – all able to find your unique iron specification. In just 10 minutes Mizuno’s Swing DNA system can shortlist the best matched 3 irons shafts – from over 40 options. With another 20 minutes you can test the outcomes and identify the set make up best suited to your unique Mizuno Swing DNA. Just 5-7 working days parts allowing (for most retailers) later your unique iron set can be ready for despatch from our assembly line in Scotland.

Why are some golfers still not being fitted for the right irons?

We found 6 hardcore golfers who bought their irons off the shelf rather than use up valuable playing time.
Mizuno’s European Tour fitter Simon Keeling thought 15 minutes with each of our cynics might be enough to change their ways.

What’s your Swing DNA?

  • Take three swings

    The Mizuno Shaft Optimizer is a real shaft that can be attached to any of Mizuno’s demo heads – when you hit a real golf ball. Within the Optimizer is a series of strain gauges that measures the sequence of forces your swing created by your swing. In just 3 swings the Mizuno Shaft Optimizer can measure everything we need to know – without checking or measuring the ball flight.

  • Measure critical factors

    The Optimizer’s screen displays 5 data points that create your Swing DNA. The readings are all taken from the shaft rather than the ball – so there’s no pressure to make perfect contact. Your readings for a pure strike and a miss-hit will be the same. The loads your ‘different’ swings place on the shaft are incredibly consistent.

  • Recommend custom setup

    From your Mizuno DNA – we can shortlist 3 suitable shafts for you to test (from over 50 possibilities). The system can’t factor in your personal preferences for feel and sound – that’s down to you. Though it’s a much easier process to make a personal choice from 3 well matched options. From our experience the right shaft could find you 20-30 yards in wasted distance as well as improving your consistency.

  • Clubhead Speed

    How fast the clubhead and shaft are moving during the swing.

  • Tempo

    How quickly the player transitions from the backswing to the downswing.

  • Shaft Toe Down

    A measure of the bowing of the shaft in a downward direction during the downswing.

  • Shaft Kick Angle

    The amount of shaft forward bending during the downswing motion.

  • Release Factor

    How and when the clubhead and shaft are releasing during the downswing motion.
